Bonaventura Cavalieri
Full name: Bonaventura Francesco Cavalieri.
Latin, Cavalerius (1598–November 30, 1647)
Summary:
Italian mathematician.
Known for Cavalieri's principle: volumes of two objects are equal if the areas of their corresponding cross-sections are in all cases equal.
Developed a "method of the indivisibles" to determine areas and volumes.
A significant step on the way to modern infinitesimal calculus.

Sir Isaac Newton
Born: 4 Jan 1643 in Woolsthorpe, Lincolnshire, England
Died: 31 March 1727 in London, England
Summary:
Greatest English mathematician of his generation.
Laid the foundation for differential and integral calculus.
Work on optics and gravitation make him one of the greatest scientists the world has known.

Summary:
English physicist and mathematician.
Culminating figure of the scientific revolution of the 17th century.
Optics: discovered the composition of white light.
Mechanics: 3 laws of motion,
law of universal gravitation.
Mathematics: discoverer of calculus.
Wrote: Philosophiae Naturalis Principia Mathematica (1687),

Sir Isaac Newton (4 January 1643 – 31 March 1727) [ OS: 25 December 1642 – 20 March 1727]
Summary:
English physicist, mathematician, astronomer, alchemist, and natural philosopher.
Regarded by many as the greatest figure in the history of science.
Philosophiae Naturalis Principia Mathematica (1687)
describes universal gravitation and the three laws of motion.
Derives Kepler's laws
Enunciated conservation of momentum and angular momentum.
Inventor of the reflecting telescope.
Discovered the spectrum when white light passes through a prism.
Argued that light is composed of particles.
Formulated an empirical law of cooling, studied the speed of sound, and proposed a theory of the origin of stars.
Shares the credit with Gottfried Leibniz for the development of calculus.
The generalized binomial theorem, "Newton's method" for approximating the zeroes,
and contributed to the study of power series.
Lagrange often said that Newton was the greatest genius who ever lived.
English poet Alexander Pope: "Nature and nature's laws lay hid in night;
God said "Let Newton be" and all was light".
